For your awwww moment for today, watch the charming way Brian Williams announced Wednesday that his daughter, Allison Williams, has been cast as the lead in NBC’s upcoming live production of “Peter Pan.”

Apparently, it’s a role that the “Girls” star was born to play.

Christopher Walken had already been cast as Captain Hook for the production that will air on Dec. 4.

“Peter Pan Live,” based on the original Broadway musical, follows NBC’s ratings smash, “The Sound of Music Live,” last December with Carrie Underwood. Though Underwood’s performance was panned by some critics, the show attracted nearly 20 million viewers.

On Wednesday, Williams reported Allison’s casting without mentioning that she is his daughter. It looked like any other news report until he showed a picture of Allison as a toddler wearing a Peter Pan costume.

“Family members confirm she's been rehearsing for this role since the age of three, and they look forward to seeing her fly,” he said with a straight face.

Yes she’ll fly, but can she sing? “Girls” fans have heard her on the show’s soundtrack and the Yale grad sang on a 2010 viral video called “Mad Men Theme Song ... With a Twist.” Watch it below.

“She’s wanted to play Peter Pan since she was about 3, “so this is a dream come true,” Allison said in a statement Wednesday.

“It’s such an honor to be a part of this adventure, and I’m very excited to get to work with this extraordinarily talented team. And besides, what could go wrong in a live televised production with simultaneous flying, sword fighting and singing?”
